Do you know what it is like to have a young child tell you exactly how something works, or someone who you think knows nothing about a subject recite knowledge about that subject?
I am always amazed at the knowledge some people pick up about things which we do not associate them with; the Apostles picked up a lot of knowledge from Christ.
When we show we are willing to tell people all we know about Christ, they will most likely stop and listen – just because they hear something different.
